CHABAHAR PORT DEAL

India and Iran have collaborated on key projects, most notably the Chabahar port in southeastern Iran that was inaugurated in December.

The port has been touted as a way for India to establish trade routes that bypass its Pakistan, but the project has seen delays.

India has been a key purchaser of Iranian oil and gas, and maintained trade ties even as sanctions were imposed on Iran over its nuclear programme between 2012 and 2016.
